Exterior Waterproofing and Crack Repair in Barrie
A homeowner in Barrie noticed damp streaks appearing on the basement walls after heavy rain and saw minor widening of a horizontal crack in the foundation. Understanding that this was more than a simple moisture issue — it was both a structural crack and a failing exterior barrier — our team recommended a combined approach: full external waterproofing paired with crack repair. Drawing on practices seen in expert projects involving wall-crack injection and exterior membrane systems.
The Combined Solution: Crack Repair + Exterior Waterproofing
First, we exposed the site by excavating along the problem wall down to the footing. The visible horizontal crack was widened slightly and cleaned. We injected a structural epoxy resin to restore the concrete’s integrity, followed by a polyurethane gel to seal any active moisture paths. For the exterior treatment, we applied a rubberized membrane over the cleaned wall, then covered it with a protective dimple board that channels water down toward the footing. We replaced outdated drainage tile with new perforated weeping tile wrapped in geotextile fabric and surrounded by ¾-inch clear gravel to improve free drainage away from the foundation wall. This dual approach ensures both the crack is sealed and the wall’s exterior is fortified against groundwater pressure.
Result: Dry, Secure Basement and Peace of Mind
After backfilling and restoring the surface, we ran a controlled water-flow test to confirm no seepage through the repaired crack and verified that water was exiting through the new drain tile system as intended. The homeowner now reports no visible dampness, no musty odours, and has regained full use of the lower level without concern for rain- or snow-melt-driven water intrusion. The combination of expert crack injection and exterior waterproofing has provided long-term protection for the Barrie home’s foundation — addressing both the symptom and the root cause of the moisture problem. The property’s value and comfort were preserved, and the homeowner now feels confident through every season.
